Hi Michelle,
Volume 3 of the very young lessons contains picture study/narrations (can be oral and written or just oral), copywork, capitalization work, subject/predicate of a sentence, sentence writing, singular and plurals, memory work, nouns, verbs, punctuation marks, creative expression and creative writing. (Volume 2 in this series contains more advanced phonics lessons like the sound “oi” , “oy” makes and “ow”, “oa” for the long o sound…beyond the simple consonant sounds…plus picture study/narration, copywork, etc.)
The elementary level book 1 begins with what looks like some review of what is in Volume 3 of the very young and contains picture study/narration, copywork and creative writing and introduces adjectives, adverbs, possessive nouns, synonyms, antonyms, homophones, apostrophe, contractions,initals and abbreviations, pronouns, sentence combining, run on sentences, lyric poetry, alphabetizing.
We have Volumes 2 and 3 of the Very Young and Volume 1 of the Elementary book if you have further specific questions.
Our 7 year old was reading, but still needed some of the advanced phonics, so that’s why we started her in V2 of very young.
